TROLLEY..

SPECIFICATION forming part of Letters Patent No. 783,458, dated February28, 1905.

Application filed December Z3, 1904:. Serial No. 238,080.

To (rf/,Z whom, 'it 'm/rty/ concern:

Be it known that I, J AMES A. NORTON, a citizen of the United States,residing at Wilkesbarre, Luzerne county, State of Pennsylvania, haveinvented certain new and useful Improvements in Trolleys, of which thefollowing is a specilication.

The present invention relates to improvements in trolleys, and has forits object to provide a construction in which any looseness due towearing of the parts may be compensated, so that the wheel may runfreely and evenly and without unnecessary noise or vibration.

A further object is to provide a construction which will not requirefrequent attention to maintain proper' lubrication of the moving partsand to provide for readily removing and replacing the wheel of thetrolley.

Referring to the accompanying' drawings,

Figure l is a sectional view of a trolley-head constructed in accordancewith this invention. Fig. '2 is a viewtaken on the line 2. 2 of Fig. 1looking in the direction of the arrow. Fig. 3 is an elevation of one ofthe hub-sections of the wheel. Fig. 4: is a detail view of theaneans'for connecting' the members of the harp.

Referring to the drawings, 1 designates the pole or staff of a trolley,which maf,1 be of any suitable construction and which is provided at itsupper end with a harp or wheel support consisting of two members 23,-the latter being pivotally connected with the former at a point 4,whereby it may be swung laterally and downwardly to permit removal ofthe wheel-center 5. The latter is supported by and between twohub-sections 6, which are mounted to turn about suitable bearings 7,attached to the sides of the harp. As shown, each of said hub-sectionsis provided at its center with an inwardly-extending boss 8, having aflattened face or surface 9, the wheelcenter 5 having suitable recessesformed in its opposite faces to receive such bosses, whereby the saidcenter piece and hubs are connected to rotate together. Each of thehub-Sections is provided with an outwardly-extending peripheral fiange10, and the space inclosed by such liange is divided by partitions orwebs 11 to providea plurality of lubricant-receptacles 12 andintermediate radiallyextending' passages or guides for adjustablebearing-blocks 13. ln the embodiment of the invention shown in thedrawings each of the hub-sections is provided with three of suchlubricant-compartments and three of the bearing-blocks, the latter beingadjustable radially of the hub by suitable screws '14. Preferably eachof said blocks consists of a metal bodyhaving its inner face madeconcave to conform to the surface of the bearing 7 on which it ismounted, and each of said blocks is shown as having' a plurality ofgrooves or recesses at its inner end, in which are arranged suitablebodies 1'5, of rawhide or similar material. Each of thelubricant-chambers 12 communicates with the passage in the hub throughwhich the bearing 7 extends by means of openings 17, whereby as thewheel revolves lubricant is freely supplied from such chambers to thebearings. By means of the adjusting-screws 14 the blocks 18 aremaintained y in contact with the journal 7, and any wear consequent onuse can be compensated for by adjusting said screws.

Means are provided 'for detacliably holding theswinging member 3 of theharp in the position shown in Fig. l. Various means may be employedV forthis purpose, that illustrated being' a transverse bar 20, extendingthrough suitable apertures in the harp members yand secured in positionby 4cutter-pins 21 22. By removing' either' pin 21 22 the bar 2() can bewithdrawn from engagement with the harp and the swinging side thereoflreadily moved outwardly. In such outward movement the hub-section 6adjacent said swinging' side of the harp will Ibe withdrawn from theother parts of the wheel, said hub-section being supported on thebearing 7, as will be evident from an examination of Fig. 1. Thewheelcenter can then be readilydrawn 'from the other hub-section and anew center substituted, if desired. To remove either of the hub-sectionsafter the parts have been disengaged as above described, theadjusting-screws 14 are withdrawn, so that the blocks 13 are not pressedclosely against the bearing 7, and the hub-section can then be readilywithdrawn from the bearing.

Having thus described the invention, what I claim is- 1. In a trolley,the combination with a harp or wheel-fork, having a rigid side memberand a swinging side member, of a bearing rigidly connected with andextending in,- wardly from each side of the harp, a wheel comprising asectional hub and a center detachably connected to said hub, thehub-sections being mounted to rotate on said bearings avnd each providedwith a plurality of radially-extending passages, bearing-blocks arrangedwithin said passages, means for adjusting said blocks toward the axis ofthe wheel, and means for detachably connecting the members of the harp.

2. 1n a trolley, the combination with a harp or wheelefork, having arigid side member and a swinging side member, of a bearing rigidlyconnected with and extending inwardly from each side or' the harp, awheel comprising a sectional hub and a center detachably connected tosaid hub, thehub-sections being mounted to rotate on said bearings andeach provided with a plurality of radially-extending passages,bearing-blocks arranged within said passages, adjustingscrews mounted inbearings at the outer ends of said radial passages in the hub andadapted to move said blocks toward the wheel-axis, and means fordetachably connecting' the members of the harp.

3. In a trolley, the combination with aliarp or wheel-fork, having arigid side member and a swinging side member, of a bearing attached toand extending inwardly from each side of the harp, a wheel comprisingtwo hubdisks adapted to rotate on'said bearings and a center detachablyconnected to said-disks to rotate therewith, each of said hub-diskshaving formed therein a plurality of radially-extending passages,bearing-blocks fitted in said passages and adapted to be pressed againstthe bearing on which the disk rotates, means for applying lubricant tothe bearing at points between the said radial passages in the hubdisks,and means for detachably connecting the members oi' the harp.

4. In a trolley, the combination with a harp or wheel-fork, having arigid side member and a swinging side member, of a bearing attached toand extending inwardly from each side of the hub, a wheel-hub mounted torotate on said bearings, said hub having about each bearing a pluralityof radially-extending passages and intermediate lubricant-receptacles,the lubricant-receptacles having ducts 6C opening through the innersurface of the hub, bearing-blocks fitted in said radial passages, meansfor adjusting said blocks toward the bearing on which the hub-disk ismounted, a wheel adapted to be detachably engaged with said hub torotate therewith, and means for detachably connecting the members of theharp.

5. ln a trolley, the combination with a harp or wheel-fork, having arigid side member and a swinging side member, of a bearing at 70 tachedto and extending inwardly from each side of the harp, a sectionalwheel-hub having a section mounted to rotate on each of said bearings,and havingI a lubricant-receptaclev formed in each section andcommunicating with the space surrounding the bearing on which thehub-section is mounted, means adjustable radially of. the hub formaintaining it in proper position on said bearings, a wheel adapted tobc detachably engaged with the 8d huh to rotate therewith, and means fordetachably connecting the members of the harp.

In testimony whereof` 1 have signed my name to this specification in thepresence of two subscribing witnesses.
